The parameters of the circuit in Figure P4.36 are \(R_{S}=4 \mathrm{k} \Omega, R_{1}=850 \mathrm{k} \Omega\), \(R_{2}=350 \mathrm{k} \Omega\), and \(R_{L}=4 \mathrm{k} \Omega\). The transistor parameters are \(V_{T P}=-1.2 \mathrm{~V}\), \(k_{p}^{\prime}=40 \mu \mathrm{A} / \mathrm{V}^{2}, W / L=80\), and \(\lambda=0.05 \mathrm{~V}^{-1}\).

(a) Determine \(I_{D Q}\) and \(V_{S D Q}\).

(b) Find the small-signal voltage gain \(A_{v}=v_{o} / v_{i}\).

(c) Determine the small-signal circuit transconductance gain \(A_{g}=i_{o} / v_{i}\).

(d) Find the smallsignal output resistance \(R_{o}\).
